LEM ART and ARU series Rogowski coils

Wednesday, 12 February, 2020 | Supplied by: Fastron Electronics



LEM’s ART and ARU series are Class 0.5 Rogowski coils for electronic measurement of AC current with galvanic separation between the primary power circuit (power) and the secondary measurement circuit. The company’s Perfect Loop Technology is designed to reduce position and proximity error compared to traditional coils.

The flexible current transformers are widely used for transformer condition monitoring, power metering, power quality analysis and fault detection. Their split core design provides easy installation for retrofit applications or installations with high load currents, multiple busbars or limited space.

Combined with the AI-PMUL multi-range integrator and signal conditioner module, the user can measure from 100 to 5000 A user selectable, adjust the input sensitivity from 22.5 to 120 mV/kA and even output true RMS process measurements including 0–5 V, 0–10 V, 0–20 mA and 4–20 mA. Traditional power meters outputs included are 0.333 and 0.166 V, with a soon-to-be-released dedicated 1 A integrator.
